A woman that is 6 ft tall casts a shadow that is 18 ft long. Find the height of a car that casts a 12 ft shadow.

Hello! To solve this, we can write and solve a proportion. Set it up like this: 6/18 = x/12. This is because we know the heights of the shadows, but not how y’all the car is and we need to group them up to get the right answer. Cross multiply the values in order to get 72 = 18x. Divide each side by 18 to isolate the variable. x = 4. There. The car is 4 feet tall.

It should be 4 feet tall, because if the woman casts a shadow 3 times her height than a car with a 12 foot tall shadow should be four feet tall
